WINDOW SCREEN, CURTAIN, A'N'Cb THE LIKE.

Specification of Letters Patent.

Patented July 29, 1913.

Application filed March 13, 1911. Serial No. 613,990.

Be it known that I, WILLIAM B. KnArr, a citizen of the United States, residmg at Paterson, inthe county of Passaic and State 5 of New Jersey, have invented certain new and useful Improvements in Window Screens, Curtains, and the Like, of which the following is a specification. I

My present invention relates to certain improvements in screens, curtains and the like appertaining to an invention forming the subject of Letters Patent No. 963,900,v

issued to me July 12th, 1910. The objects aimed at and advantages secured by mysaid improvements -w'i-ll be readily understood by those skilled in the arts upon reference to the following specification in connection with the accompanying drawings, wherein,

Figure 1 i'san inside view of a window casing having my invention applied thereto; Fig. 2 is a vertical sectional view of that part of what is shown in Fig.- 1 which im mediately includes themeetin g rails of the two sashes, the uppenhorizontal rail of the frame'for the screen, and the upper partlof the screen; Fig. 3 is a fragmentary horizontal sectional view taken just above one of the clamps shown in Fig. I for securing the improved screen structure in place; Fig. 4. shows, partly in section and on a larger scale, the clamp shown in Fig. 3; Fig. 5 is a fragmentary rspective view illustrating the structure 0 the screen proper and also showing an improved lift; Fig. 6 is a fragfm' entary horizontal sectional .View showing the relation of parts of the screen proper to the frame in which the screen moves; Fig.

.7 is a fragmentary perspective view illustratingthe disposition of a certain angular Strip; Fig. 8 is an inside view, partly in sectlon, of a wlndow casmg provided wlth a modified form of my lnvention; Fig. 9 1s a I vertical sectional view of the upper portion of the casing shown in Fig. 8; Figs. 10 and 11 are perspective views illustrating details in .Figs. 3 and 9; Fig. 12 is a View in elevat-ion, partly in section, illustrating a modification of what is'shown in 11;'Fig. 13

is a vertical sectional fragmentary view of another detail appertaining to Fig. 8; and, Figs. 14. and 15 arelongitudinal and crosssectional views of an improved spring roller a designates the window casing, b and b "Eac upon which the screen or curtain is wound;

the lower and upper sashes, respectively, and

wound the screen or-curtain g. The frame d is removable from the casin a, but isnormally held in place by two 0 amps secured to the inner ad oining face of the frame and ada ted to bear agalnst the stop beads a. clamp comprises a bracket 72. in which is journaled a cam i'havingalever or handle j and carryin a presser iewhich termimates in a broad foot l adapted to bear against the face of the stop bead '0. The- -foot 2- of the presser is extended outwardly as shown in Fig. 4 so as to reach between the frame d and the molding 0 of the casing (2; thus the foot Z of the presser acquires an ample purchase on the casing although the surface of the latter which is im inged by said foot may be beveled forw'ar as is the case with the molding c in Fig. 4. In securing the frame in placethe handles are turned in one direction to force each foot Z into contact with the stop bead; upon turn ing the handles in the opposite direction the clamping action will be relieved, so that the frame may be removed.

The sides of the frame d, as in my patented construction, comprise two strips d and d (Fig. 6) and said sides have 0 posed vertical groovesmwhich receive tiie edges of the screen or curtain g. The free edge of the screen or curtain is held in. a

cross-piece 11., comprising two strips n and n between which said edge of the screen is received,-togetherwith a flat metallic reinforcing strip 0 whose ends, project from the ends of the cross-piece to form.fins 1). These fins are received by the grooves m in the sides of the frame (if, and to insure a smooth and accurate yetsnug working of the cross-piece with respect to said sides, the strip n has projections at its ends which overlap the sides of the frame a? (Fig. 6). Further, to insure'a closed and nicely fitting joint between the cross-piece n, and the upper horizontal rail of the frame 03,

the said rail and cross-piece n have the beveled coactin'g lips d and n (Fi 2);

In order to close off any possi 1e openings secured to the free edge of said fabric, and

having its ends guided in said grooves, the

adjoining portions of said rail and cross piece having for their entire length mating beveled lips adapted to overlap each other when said cross-piece abuts against the rail, substantially as described.

3. The combination, with the windoWcasing and a sash movable vertically therein, of an'open rectangular frame fitted in the casing ahd lying in close relation to and parallel with the inner face of the sash, a

horizontal roller journaled in said frame adjacent one of its horizontal portions, a

fabric wound on said roller and adapted when unwound to extend to the other horizontal portion of said frame rmeans for securing said frame removably in position, and cross-sectionally angular strips re spectively fitted in the angles between the sash and the sides of the casing and each having one wall thereof overlapping the adjoining side of said frame, substantially as described.

4. The combination ofa frame having parallel sides formed with opposite'vert-ical grooves, a horizontal roller journaled in said frame, a fabric Wound on said roller, and a horizontal cross-piece secured to the free horizontal edge of'said fabric and comprising flat strips 02 n and a fiat reinforc ing StI'lP4O interposed between the strips 71' n? and having its ends projecting beyond the ends of the latter strips and'entering said grooves, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

WILLIAM B. KNAPP.
